Description

【0001】
【発明の属する技術分野】
本発明は、殺菌消毒剤、抗菌性薬剤及び抗菌性材料に関する。さらに詳しくは、本発明は、皮膚刺激、発赤、肌荒れや皮膚感作などの皮膚障害がなく、低濃度でも有効な殺菌及び抗菌効果を有する殺菌消毒剤、抗菌性薬剤及び抗菌性材料に関する。
【0002】
【従来の技術】
従来から一般的に使用されている界面活性剤系殺菌消毒剤、ビグアニド系殺菌消毒剤、フェノール系殺菌消毒剤などは、短時間、すなわち、数十秒間の菌との接触により殺菌作用を示すように常用濃度が設定されている。例えば、界面活性剤系殺菌消毒剤としては、塩化ベンザルコニウム、塩化ベンゼトニウム、ジデシルジメチルアンモニウム塩、アルキル(C12〜C18)トリメチルアンモニウム塩、塩酸アルキルポリアミノエチルグリシンなどが挙げられ、これらの殺菌消毒剤の医療機関における常用濃度は0.2重量%であって、水溶液又はエタノール溶液として使用されている。この常用濃度において、界面活性剤系殺菌消毒剤は皮膚を刺激しやすく、肌荒れや発赤、皮膚感作などの皮膚障害が起こることが報告されており、安全上使用濃度の低下が望まれているが、皮膚障害を起こさない程度にまで使用濃度を下げると、安全な殺菌効果は得られない。さらに、界面活性剤系殺菌消毒剤は、緑膿菌に対する殺菌効果が弱いという欠点も有している。
そこで、十分な殺菌作用を示す濃度においても皮膚障害の少ない殺菌消毒剤の使用が試みられている。例えば、各種の文献[Rembaum,A.:Appl.Polym.Symp.,22,299(1973)、Vucetic,J.J.,Vandjel,V.H.,Janic,M.D.:Glas.Hem.Drus.Beograd,42,289(1977)、Ikeda,T.,Yamaguchi,H.Tazuke,S.:J.Bioact.Comp.Polym.,5,31(1990)]などに記載されている第4級アンモニウム塩系のカチオンポリマーは、抗菌性を有し、界面活性剤系殺菌消毒剤の数十倍の濃度で使用しても、皮膚刺激、発赤、肌荒れや皮膚感作などの皮膚障害は起こらない。しかし、これらのカチオンポリマーは、界面活性剤系殺菌消毒剤の常用濃度と同濃度で使用した場合、短時間の接触による殺菌効果は界面活性剤系殺菌消毒剤よりも劣り、短時間接触での殺菌効果を得るために濃い濃度で使用すると、粘着性が非常に強く残って使用に耐えがたいという問題がある。このような状況から、皮膚障害が少なく低濃度でも有効な殺菌効果を示す殺菌消毒剤及び抗菌性薬剤が求められている。
【0003】
【発明が解決しようとする課題】
本発明は、皮膚刺激、発赤、肌荒れや皮膚感作などの皮膚障害がなく、低濃度でも有効な殺菌及び抗菌効果を有し、かつ緑膿菌に対しても優れた効果を発揮する殺菌消毒剤、抗菌性薬剤及び抗菌性材料を提供することを目的としてなされたものである。
【0004】
【課題を解決するための手段】
本発明者らは、上記の課題を解決すべく鋭意研究を重ねた結果、主鎖中にヘテロアルキレン構造を有する高重合度の第4級アンモニウムポリマーが、従来の殺菌消毒剤の常用濃度以上でも皮膚障害を起こさず、塩化ベンザルコニウムと同程度以上の殺菌効果を有し、さらに、従来の界面活性剤系殺菌消毒剤を、皮膚障害を起こさない程の低濃度で併用することにより、菌体との短時間接触においても十分な殺菌効果を発揮することを見いだし、この知見に基づいて本発明を完成するに至った。

【実施例】
以下に、実施例を挙げて本発明をさらに詳細に説明するが、本発明はこれらの実施例によりなんら限定されるものではない。
なお、カチオンポリマーの重合平均分子量は、水系ゲル・パーミエーション・クロマトグラフ(GPC)[東ソー(株)、HLC−8120GPC]を用いて測定し、ポリエチレングリコールに換算して求めた。
また、殺菌効果の評価は、下記の方法にしたがって行った。
(1)試験菌
黄色ぶどう状球菌(Staphyrococcus aureus(略称S.aureus)ATCC 6538P)、メチシリン耐性黄色ぶどう状球菌(MRSA IID 1677)、メチシリン耐性黄色ぶどう状球菌(MRSA 臨床分離株)、大腸菌(Escherichia coli(略称E.coli)IFO 3301)、肺炎桿菌(Klebsiella pneumoniae(略称K.pneumoniae)IFO ATCC 4352)、緑膿菌(Pseudomonus aeruginosa(略称P.aeruginosa)IFO 3080)、セラチア菌(Serratia marcescens(略称S.marcescens)臨床分離株)の7種の菌を試験菌として用いた。
(2)試験菌液の調製
試験菌1白金耳を、ソイビーン・カゼイン・ダイジェスト(SCD)培地8mLに接種し、37℃で18時間培養したのち、この培養液1mLをSCD培地で10倍希釈した。さらに、この希釈液2mLをSCD培地100mLに接触させ、37℃でP.aeruginosaは4時間、他の菌は2時間培養し、試験菌液とした。試験菌液には、1mLあたり10〜10個の生菌数が含まれる。
(3)操作
生理食塩水を用いて殺菌消毒剤組成物の2倍希釈列を調製し、各希釈液を10mLずつ試験管に分注し、オートクレーブ滅菌を行ったのち、試験菌液を0.1mLずつ添加混合した。菌と殺菌消毒剤組成物を1分間接触させたのち、この接種液を、予め滅菌した3本のSCD−LP(レシチン・ポリソルベート)培地(各9mL)に0.1mLずつ添加混合した。これを37℃で20時間培養したのち、培地の濁りの有無を判定した。培地が透明であれば菌の発育を認めないとして−、濁れば菌が発育したとして+とし、3本のうち2本以上の判定を採用した。−判定がついた最小濃度を最小殺菌濃度(MBC)とした。
さらに、皮膚刺激性試験は、下記の方法により行った。
すなわち、殺菌消毒剤0.02mLをろ紙上に置き、男性、女性各5人ずつ(男性A〜E及び女性F〜Jとする)の左上腕屈側に閉鎖法で貼付した。貼付30分後及び24時間後に、一次刺激性を4段階で判定した。判断基準は下記の通りとした。
判定基準
−:陰性(反応なし)。
±:紅斑のみ。
+:紅斑に加えて、湿潤又は丘疹が生じる。
++:紅斑、浮腫、丘疹又は小水疱が顕著にみられる。

BACKGROUND OF THE INVENTION
The present invention relates to a disinfectant, an antibacterial drug and an antibacterial material. More specifically, the present invention relates to a bactericidal disinfectant, an antibacterial drug and an antibacterial material which have no skin damage such as skin irritation, redness, rough skin and skin sensitization and which have an effective bactericidal and antibacterial effect even at low concentrations.
[0002]
[Prior art]
Conventionally used surfactant-based disinfectants, biguanide-based disinfectants, phenol-based disinfectants, and the like have a bactericidal action upon contact with bacteria for a short time, that is, for several tens of seconds. The normal concentration is set in For example, the surfactant system disinfectant, benzalkonium chloride, benzethonium chloride, didecyldimethylammonium salts, alkyl (C 12 ~C 18) trimethyl ammonium salts, such as hydrochloric alkylpolyaminoethylglycine and the like, these The usual concentration of a disinfectant in a medical institution is 0.2% by weight and is used as an aqueous solution or an ethanol solution. At this normal concentration, surfactant-based disinfectants are easy to irritate the skin, and skin damage such as rough skin, redness, and skin sensitization has been reported. However, if the use concentration is lowered to such an extent that does not cause skin damage, a safe bactericidal effect cannot be obtained. Furthermore, the surfactant-based disinfectant has a drawback that the disinfecting effect against Pseudomonas aeruginosa is weak.
Therefore, attempts have been made to use a bactericidal disinfectant with little skin damage even at a concentration showing a sufficient bactericidal action. For example, various documents [Rembaum, A. et al. : Appl. Polym. Symp. , 22, 299 (1973), Vucetic, J. et al. J. et al. Vandjel, V .; H. Janic, M .; D. : Glas. Hem. Drus. Beograd, 42, 289 (1977), Ikeda, T .; Yamaguchi, H .; Tazuke, S .; : J. Bioact. Comp. Polym. , 5, 31 (1990)] and the like, the quaternary ammonium salt-based cationic polymer has antibacterial properties, and even when used at a concentration several tens of times higher than that of a surfactant-based disinfectant, Skin damage such as skin irritation, redness, rough skin and skin sensitization does not occur. However, when these cationic polymers are used at the same concentration as the normal concentration of a surfactant-based disinfectant, the disinfection effect due to short-time contact is inferior to that of a surfactant-based disinfectant, When used at a high concentration to obtain a bactericidal effect, there is a problem that the adhesiveness remains very strong and it is difficult to withstand the use. Under such circumstances, a bactericidal disinfectant and an antibacterial agent that have an effective bactericidal effect even at a low concentration with little skin damage are demanded.
[0003]
[Problems to be solved by the invention]
The present invention does not cause skin irritation such as skin irritation, redness, rough skin, and skin sensitization, has an effective sterilization and antibacterial effect even at low concentrations, and exhibits an excellent effect against Pseudomonas aeruginosa It was made for the purpose of providing an agent, an antibacterial drug, and an antibacterial material.
[0004]
[Means for Solving the Problems]
As a result of intensive studies to solve the above problems, the present inventors have found that a quaternary ammonium polymer having a high degree of polymerization having a heteroalkylene structure in the main chain can be used at a concentration higher than the conventional concentration of conventional disinfectants.
